When the back-up processing is set (YES at step 108), a “data select image screen” as shown in FIG. 7 is displayed on the liquid crystal display image screen 4 h of the control panel 4. On the data select image are displayed a database button 71, an address book data button 72, a setting data button 73, an image data button 74, a select button 75 and a cancel button 76 corresponding to the data (a database, address book data, setting data, image data in the hard disk drive 25) as a back-up target.
When the address book data button 72 is touch-operated by the service personnel, the address book data button 72 is lit. The lit state is represented by dots. By the touch-operating the select button 75 in this state, the address book data is selected (YES at step 110).
When the address book data is selected (YES at step 110), a “memory medium select image screen” as shown in FIG. 8 is displayed on the liquid crystal display image screen 4 h of the control panel 4. In this case, since only the USB memory 10 is set to the USB ports 8 a, 8 b for a host, that is, only the USB memory 10 is detected, the USB memory button 81, select button 83 and cancel button 84 are displayed on the “memory medium select image screen”.
When the USB memory button 81 is touch-operated by the service personnel, the USB memory button 81 is lit and the lit state is indicated by dots. By the touch-operation of the select button 83 in this state, the USB memory 10 is selected (YES at step 112).
Then, the selected address book data is read out from the hard disk drive 25 and stored in RAM 22. And the address book data in the RAM 22 is coded (step 113). This coding is done by a coding program initially stored in the ROM 23.
The coded data is stored in the selected USB memory 10 (step 114). When this storing is completed, the back-up completed character is displayed on the liquid crystal display image screen 4 h of the control panel 4 (step 115) and this back-up processing is completed.
By looking at the back-up completed character display, the service personnel judges that the address book data is stored in the USB memory 10. And the USB memory 10 is reset from the USB port 8 a for a host.
It is to be noted that, where the USB memory 10 and CD-R drive 15 are set to the USB port 8 a and 8 b for a host, a “memory medium select image screen” shown in FIG. 9 is displayed on the liquid crystal display image screen 4 h of the control panel 4 after the address book data has been selected (YES at step 110). That is, since the USB memory 10 and CD-R drive 15 are detected, a USB memory button 81, a CD-R button 82, a select button 83 and cancel button 84 are displayed on the “memory medium select image screen”.
When the CD-R button 82 is touch-operated by the service personnel, the CD-R button 82 is lit. By the touch operation of the select button 83 in this state, the CD-R drive 15 is selected (YES at step 112).
Subsequently, the selected address book data is read from the hard disk drive 25 and stored in the RAM 22. And the address book data in the RAM 22 is coded (step 113).
The coded data is stored in the selected CD-R drive 15 (step 114). When the storing of the coded data is completed, the back-up completed character is displayed on the liquid crystal display image screen 4 h (step 115). This completes the back-up processing.
By looking at the back-up completed character display, the service personnel judges that the address book data is stored in the CD-R drive 15. And the USB memory 10 and CD-R drive 15 are reset from the USB ports 8 a and 8 b for a host.
After the back-up processing is completed, the service personnel moves a newly installed image forming apparatus and the USB memory 10 is set to a USB port 8 a for a host, that is, a USB port 8 a of the image forming apparatus.
When the USB memory 10 is set to the USB port 8 a for a host (YES at step 101), a “particular mode set image screen” as shown in FIG. 5 is displayed on the liquid crystal display image screen 4 h of the control panel 4. When the particular mode button 51 of the “particular mode set image screen” is touch-operated by the service personnel, the particular mode button 51 is lit. By the touch-operation of the setting button 52 in this state, a particular mode is set (YES at step 103).
When the particular mode is set (YES at step 103) and the power supply switch 7 of the apparatus body 1 is turned ON (step 104), a load module (program) is read into the apparatus body 1 via the USB port 8 a for a host (step 105). The thus read load module is stored in the RAM 22 and started (step 106).
By the starting of the load module, a “processing set image screen” as shown in FIG. 6 is displayed on the liquid crystal display image screen 4 h of the control panel 4. When the restore button 62 on the “processing set image screen” is touch-operated by the service personnel, the restore button 62 is lit. By the touch-operation of the setting button 63 in this state, the restore processing is set (NO at the step 108, YES at step 116).
When the restore processing is set (YES at step 116), the “memory medium select image screen” as shown in FIG. 8 is displayed on the liquid crystal display image screen 4 h of the control panel 4 (step 117). When the USB memory button 81 of the “memory medium select image screen” is touch-operated, the USB memory button 81 is lit. By the touch-operation of the select button 83 in this state, the USB memory 10 is selected (YES at step 118).
When the USB memory 10 is selected (YES at step 118), the address book data stored in the USB memory 10 is read out (step 119). The thus read out address book data is stored in the RAM 22. And the address book data in the RAM 22 is decoded (step 120). This decoding is done under a decode program initially stored in the ROM 23.
The decoded data is stored in the hard disk drive 25 (step 121). When this data storing is completed, a restore completed character is displayed on the liquid crystal display image screen 4 h of the control panel 4 (step 122). In this way, the restore processing is completed.
By looking at the restore completed character display, the service personnel judges that the address book data is stored in the hard disk drive 25 of the apparatus body 1, and the USB memory 10 is reset from the USB port 8 a for a host.
It is to be noted that, where the USB memory 10 and CD-R drive 15 are set to the USB ports 8 a and 8 b for a host, the “memory medium select image screen” as shown in FIG. 9 is displayed on the liquid-crystal display image screen 4 h of the control panel 4 after the restore processing has been set (YES at step 116). That is, since the USB memory 10 and CD-R drive 15 are detected, the USB memory button 81, CD-R button 82, select button 83 and cancel button 84 are displayed on the “memory medium select image screen”.
When the CD-R button 82 is touch-operated by the service personnel, the CD-R button 82 is lit. By the touch-operation of the select button 83 in this state, the CD-R drive 15 is selected (YES at step 112).
When the CD-R drive 15 is selected (YES at step 118), the address book data stored in the CD-R drive 15 is read out (step 119). The thus read-out address book data is stored in the RAM 22. And the address book data in the RAM 22 is decoded (step 120).
The decoded data is stored in the hard disk drive 25 (step 121). When this data storing is completed, the restore completed character is displayed on the liquid crystal display image screen 4 h (step 122). In this way, the restore processing is completed.
By looking at the restore-completed character display, the service personnel judges that the address book data is stored in the hard disk drive 25 of the apparatus body 1. And the USB memory 10 and CD-R drive 15 are reset from the USB ports 8 a and 8 b for a host.
When, as set out above, the USB memory 10 is set to the host USB port 8 a and back-up processing is set on the control panel 4, data in the hard disk drive 25 is read out based on the program in the USB memory 10 and stored in the USB memory 10. The data which is read out from the hard disk drive 25 can also be stored in the CD-R drive 15 set to the USB port 8 b.
Where the USB memory 10 and CD-R drive 15 are set to the USB ports 8 a and 8 b and restore processing is set on the control panel 4, data stored in the USB memory 10 or CD-R drive 15 is read out based on the program in the USB memory 15 and stored in the hard disk drive 25.
The data stored in one image forming apparatus is readily and positively copied/registered on another image forming apparatus through the USB memory 10 (and CD-R drive 15). It is not necessary for the service personnel to perform any cumbersome manual registering operation. It is thus possible to alleviate any larger burden on the service personnel.
The data stored in one image forming apparatus can be readily and positively copied/registered on another image forming apparatus without use of the network. Further, it is not necessary for the service personnel to connect his or her terminal (personal computer) to the network. It is also possible to prevent any outside leakage of important data on the network and to obtain high security.
Since the data in the hard disk drive 25, after being coded, is read out of the apparatus body 1 and the read-out data, after being decoded, is registered into the body 1, it is possible to prevent any risk of data leakage and also to obtain a high security level.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiment shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
